I enjoy asking students to guess what 3 numbers I am thinking of, given that they have a mean of 5 (or some other value). I tell them that they are "close" on their first two guesses (e.g., it was, "-20", rather than "20"). Of course, they quickly realize that once I have given them 2 numbers, they know the third.
